Little People Big World started with all four Roloff siblings starring on the TLC series, but only one remains on the current season, and we have all of the details on what the reality star children are up to now. Matt and Amy Roloff's four children Jeremy, Zach, Molly, and Jacob grew up on Little People Big World as the series began broadcasting their lives over 15 years ago in 2006. Although only Zach has remained on the series, Jeremy, Molly, and Jacob have all been living their lives to the fullest off-screen while Little People Big World celebrates its 22nd season. Here's everything the Roloff siblings have been up to since they departed from their family's revolutionary reality television series.

Zach

Twins Zach and Jeremy are the oldest of the Roloff offspring at 31 years old. Even though they share the same birthday of May 10, 1990, Zach and Jeremy have led very different lives. For starters, Zach remains on Little People Big World, while Jeremy decided to leave the TLC series in 2018. Moreover, Zach has stayed close to his family's farm. In 2015, Zach got married to his wife Tori. Since their marriage, the couple has remained strong and welcomed two children. The couple's oldest child, Jackson, is four years old and was born on May 12, 2017 - months after the death of Zach and Tori's dog, Sully. Jackson's younger sister, Lilah, was born on November 19, 2019, meaning that she will celebrate her second birthday this fall. In 2018, the reality couple purchased a home in Oregon not too far from the farm where Zach grew up on.

Jeremy

After ending his 13-season run on Little People Big World, Jeremy has been busy working as an entrepreneur and growing his family. Jeremy and his wife Audrey Mirabella Botti have two children, Ember Jean and Bode James. Ember will turn four on September 10, while Bode celebrated his first birthday on January 8. In addition to working on their family, Jeremy and Audrey have found success as authors and podcasters. Even though fans had hoped Jeremy and Audrey would take over the Roloff farm, the couple stuck to producing entertainment instead. In November 2018, Jeremy and Audrey's podcast Behind The Scenes debuted on Apple Podcasts and Spotify. The podcast remains active, as the 94th episode was released in early March 2021. The former pair of reality stars also wrote a New York Times Bestseller, A Love Letter Life: Pursue Creatively, Date Intentionally, Love Faithfully, in 2019.

Molly

Molly's departure from Little People Big World was less established than her older brother Jeremy's. 27-year-old Molly never officially announced her exit from the TLC series, leaving the fans without any concrete reasoning for her abrupt absence. Although it is one of Little People Big World's best-kept secrets, one logical explanation for Molly's disappearance from her parents' hit reality show is her distance from the Roloff farm. In August 2017, Molly married Joel Silvius. After tying the knot, Molly and Joel moved to Spokane, Washington, which is over 5 hours of distance from her family's Portland farm. Molly has kept her life after reality television relatively private, but she does appear on her siblings' social media and episodes of Little People Big World occasionally.

Jacob

The youngest Roloff child is 24-year-old Jacob. Since leaving the show, Jacob got married to Isabel Sofia Rock in September 2019. Additionally, Jacob has utilized his Instagram as a way to advocate for causes he believes in since leaving the show. With 327,000 followers, Jacob regularly promotes information on the PRO Act - a bill that would support worker's rights across the country. He is also working on Unionizing Cannabis workers in Oregon. In addition, Jacob revealed that a Little People Big World producer sexually assaulted him, which he revealed during an IG post. While it is unclear where Jacob and Isabel have settled since leaving the farm, all of the issues Jacob cares about can be found on his social media.

Although most of the Roloff children didn't stick around the farm, they have led fascinating lives off-screen. From Jeremy writing a bestselling book to Jacob sharing his experience as a survivor, the Roloff siblings have done well for themselves. While it is unlikely Jacob or Jeremy will return to reality television, Zach and Molly will likely appear in upcoming episodes of Little People Big World.
